Definitions

  • the present invention relates to ink jet printers, and, more particularly, to ink jet printers including a printhead with a plurality of jetting heaters and at least one substrate heater.
  • An ink jet printer typically includes a printhead having a nozzle plate which is connected to and mounted in spaced apart relationship relative to a substrate.
  • the nozzle plate includes a plurality of ink emitting orifices which are respectively disposed in association with a plurality of jetting heaters mounted on the substrate.
  • jetting heaters When a particular jetting heater is actuated or fired, ink disposed adjacent thereto rapidly expands to form a vapor bubble. Ink is expelled through the ink emitting orifice by the bubble and is jetted onto the print medium.
  • Printhead 10 includes a nozzle plate 12 having a plurality of ink emitting orifices 14 formed therein.
  • ink emitting orifices 14 are formed in two vertical columns with fifty two ink emitting orifices 14 in each column, (i.e., a 2 x 52 array).
  • the majority of ink emitting orifices 14 are labeled with an individual index number between 1 and 104 in Fig. 1.
  • Printhead 10 also includes a substrate 16 which is connected to nozzle plate 12.
  • a plurality of jetting heaters 18 are mounted on substrate 16 and positioned relative to respective ink emitting orifices 14. More particularly, each of the plurality of jetting heaters 18 is positioned substantially in axial alignment with a respective ink emitting orifice 14. Actuation of a jetting heater 18 rapidly heats the ink disposed adjacent thereto, and creates a gas bubble which jets ink from the associated ink emitting orifice 14.
  • Printhead 10 includes a decoder 24 which is connected with a plurality of input pins EA1 through EA5. Decoder 24 receives encoded signals through the connection with pins EA1 through EA5 and decodes the encoded signals for selectively actuating transistors 22 which are associated with respective ink jetting heaters 18. Decoder 24 also includes an input connected to pin BSELECT on printhead 10. Decoder 24 receives a signal for selection and deselection of printhead 10 through the connection with pin BSELECT, as will be described in more detail below. Decoder 24 may include a number of configurations capable of decoding the encoded signals received from pins EA1 through EA5. For example, decoder 24 may include a combination of transistors, which are configured to decode the encoded signals received from pins EA1 through EA5.
